Sumday – a daily game: make an equation from today's date
Hi all! This is a game I made where you try to make an equation from today's date, using every digit in order. I had a substitute math teacher in middle school who did this on the whiteboard one day, and I've been doing it for fun every so often since. I was inspired by wordle to make it into a daily web game, but unlike wordle and other games in that genre, you don't need to guess one specific solution. Any valid equation works. I found that mechanic more enjoyable and let me focus on just the math. Each day does have a "canonical" solution that you can gradually reveal with the Hint…

I made a little math game named Summle2022 · summle.net · ▲189I made this game for my children to play, as they are heavily into Wordle, and I thought they'd also like something maths based! Every puzzle is solvable and has at least one solution (usually more). There is a kids mode in the settings, plus a hard mode for extra difficulty.
I made a web game that makes practicing basic arithmetic fun2024 · worchle.com · ▲161Hey, maker here. After launching a daily word search game, I randomly thought of this math game while driving. Finally got around to making it and I think it turned out pretty cool. It’s a math search game that’s meant to help you practice your quick addition, subtraction, multiplication, and division skills. I’m hoping it’ll help people (even those like me who aren’t big on math) learn and increase their speeds. (There are also some settings you can enable to make the game harder) If you try it out, please let me know if you found it fun, if you have anything you’d like me to add, or if you…

Weekle – a web app to learn how to calculate the day of the week2023 · benjoffe.com · ▲122Mentally calculating the day-of-the-week for any date in history sounds like an impossible task for a normal person, but the algorithm is actually pretty simple to learn. Although there are tutorials for this elsewhere online, and little quizzes available, there didn't seem to be anything well optimised with multiple practice modes etc. I originally created a basic version of this just for myself, but a small group of friends and family found it interesting and gave suggestions such as the daily game. Multi-lingual support is a bit rudimentary at the moment, it will only translate the month…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
